I had this problem on my 99 Alero and I had to take it to the dealer for a $520 repair. I researched this issue before taking mine to repair and all i found was the same answer. This is the best option you have to be rid of this annoying problem... Here is a step-by-step procedure:
Pry up the plastic molding from around the Radio/HeaterAC controller and from around the Gear Shifter. Detach the HeaterAC module from the molding by removing the four 7-mm hex bolts from the back side. Take out the 3 7-mm hex bolts to loosen the Radio. Put key in ignition & turn to "On" position, apply brake, and shift into "drive" or lower gear. Turn HeaterAC module to the left, sideways orientation, and pull out the Radio. Disconnect main wiring harness from back center of Radio if there is not enough slack to take the Radio out past the plastic molding. Leave the antenna connected. Look inside and to the left at the back of the Ignition Cylinder assembly. Locate the THIN YELLOW WIRE which is bundled alongside the thin white and the thin black wire. You may have to stick you hand in and fish a bit to grab this "Thin wire Trio". DO NOT mess with the main rear/downward ignition wiring harnesses (1 of which contains a Thick Yellow Wire - leave it alone).
Isolate the THIN YELLOW WIRE from the 2 others. As a precaution, RECONNECT the MAIN RADIO WIRE HARNESS, and let the Radio hang to the right side. Put the key in the ignition, and put the car back in PARK. START THE CAR. CUT THE THIN YELLOW WIRE with the car running. Tape both ends of the cut wire. Place black electrical tape over the "Security" light (less annoying). Turn off the car engine. Disconnect the Radio main wire harness to Re-Install the Radio, if necessary. You may need to crawl under the passenger-side dash to push the main wire harness back into the radio while holding the Radio from the front. The rest of the installation is the reverse of removal. YOUR LIFE JUST GOT A LOT BETTER if you want to keep driving this car !!
how do you fix security switch on a 2002 oldsmobile alero
You can't bypass or reset security system, bring it to the dealer.
I wouldn't fix it if i was you.....I have a 2000 alero, and the security system (passlock) keeps it from starting often, and it seems to be a big problem with them. So if your security system isn't working but the car is running fine I wouldn't mess with it..
That means your security system door lock is acting up. Pretty much you have to take it down to a delear
Try putting the key in the on position but dont start it wait 15 to 20 min it should start flashing security right hand corner of the dash take the key out count to ten than turn car on this is how to disable it so maybe it work turn it back on.
You don't, your computer controls your speed. If you do this, you turn your engine off.
It's probably related to your security system. If that's the case you'll need to take it to a dealer to get it cleared up. I found out after countless hours of working on my sister's Alero that they're Oldsmobile's version of the Edsel.
It probably won't start
There is no governor on this car. The speed is computer controlled by a rev limiter or fuel shutoff.
mash the emergency brake one click and that should turn them off
If you just want them off when your parked, just put on the emergency brake.
always on nomatter what i do
